IPC: C08G63/48
Abstract: 284,349. British Thomson-Houston Co., Ltd., (Assignees of Kienle, R. H.). Jan. 29, 1927, [Convention date]. Varnishes.-Resins of the glycerol-phthalic anhydride type are modified by including in the reaction mixture an unsaturated oxidizable fatty acid, particularly an acid derived from a drying oil, such as eleostearic, linolic, or linolenic acid. In one example, glycerol and phthalic anhydride are heated together and, at an intermediate stage of the reaction, one or more fatty acids derived from a drying oil, such as china-wood, linseed, or perilla oil, are added to the mixture, together with a further amount of phthalic anhydride. In another example, the phthalic anhydride and the fatty acids are melted together and the glycerol then added. The products are soluble in acetone, acetone-benzene, coal tar oil, acetone oil, butyl acetate, butyl alcohol, ethyl lactate glycol, glycol diacetate, glycol derivatives such as the monoethvl ether, benzyl acetate, triacetin, and phthalic esters such as diethyl phthalate; they are soluble also in drying oils such. as linseed, china-wood, perilla, or blown fish oil. The solutions are useful as varnish. Specifications 24254/12 and 252,394 are referred to.

In a two-stroke loop scavenged I.C. engine with exhaust and scavenging ports disposed substantially perpendicular to the cylinder axis, main scavenging ports are disposed adjacent to, and at each side of, the exhaust ports with their top edges situated approximately level with the bottom edges of the exhaust ports, and auxiliary scavenging ports of a total cross-sectional area less than that of the main scavenging ports are disposed beneath the exhaust ports. The exhaust ports 3, Figs. 1 and 6 are symmetrically arranged with their axes directed towards the cylinder axis and subtend an angle at the latter of about 90 to 130 degrees. The axes of the main scavenging ports 4, Fig. 3, intersect the plane of symmetry of the scavenging port arrangement in the region of the wall of the cylinder liner, in this case between the inner and outer boundaries of the liner. The axes of the auxiliary scavenging ports 5 intersect inside the cylinder. The axes of the scavenging ports 4 and 5 may have a slight upward inclination of 10 degrees maximum with respect to a plane perpendicular to the cylinder axis. The piston head is chamfered at its periphery to an angle a, Fig. 7, of about 10 degrees to 15 degrees which in conjunction with the exhaust ports has the effect of deflecting the emerging gas stream into the exhaust duct 6, Fig. 1, which slopes gently upwards and is provided with a rotary valve (not shown) if the engine is supercharged. In conjunction with the scavenging ports the piston chamfer results in a slight upward inclination of the incoming stream of scavenging air. The diameter d, Fig. 7, is approximately 0À75D.

Filed: 1961-08-16
Abstract: 947,902. Variable equalizers. GENERAL ELECTRIC CO. Ltd. July 11, 1962 [Aug. 16, 1961], No. 29577/61. Heading H4R. In a variable equalizer of the type comprising two impedances, the product of which is required to be kept constant, the impedances are connected into the equalizer circuit by transformers and the impedances and the transformer primaries are connected across the diagonals of a normally balanced bridge so that the one impedance and transformer circuit is isolated from the other impedance and transformer circuit. As shown, Fig. 1, the equalizer comprises a T-network 7 whose shunt arm includes the secondary of a transformer 15 whose primary is connected in series with a thermistor 33, across one diagonal of a bridge circuit 22, while the series arm is shunted by the parallel combination of a network 10 and the secondary of a transformer 12 whose primary is connected, in parallel with the thermistor 28, across the other diagonal of the bridge 22. The series and shunt elements of the equilizer thus being isolated by the normally balanced bridge. The required relation that the product of the impedances of thermistors should be constant is obtained by the method described in Specification 903,691, i.e. by feeding the heater 31 of thermistor 28 with the voltage developed across resistor 24 which voltage is the unbalance voltage of a bridge having thermistors 28 and 33 in diagonally opposite arms, this being shown more clearly in the redrawn circuit of Fig. 2. Thus a control voltage applied to terminals 5 and 6 controls the equalization whilst keeping the equalizer impedance constant. Alternative forms of circuit are suggested which replace amplifier 30 by an oscillator or by a modulator and amplifier circuit forming an oscillator whose amplitude of oscillation is dependent on the unbalance of the bridge circuit including thermistors 28 and 33. Such an oscillator is described in Specification 873,786.
